Lanyao Flocculant Decolorizer Decolorizing Agent for Textile Wastewater

The textile industry is one of the important economic sectors, including textiles and printing and dyeing. In the process of processing various raw materials into fabrics in the textile industry, various types of wastewater are generated, among which dyeing wastewater pollution is more serious. Textile printing and dyeing wastewater refers to the general term for various types of wastewater generated during the textile and printing and dyeing processing. It includes two parts: textile wastewater and printing and dyeing wastewater. Traditionally, organic wastewater generated during textile processing is also considered as a component of printing and dyeing wastewater treatment.

Printing and dyeing wastewater mainly comes from processes such as desizing, boiling, bleaching, sericulture, dyeing, printing, and finishing. The pollutants mainly refer to various fiber materials and dyes, textile slurries, chemical agents, surfactants, and various finishing agents used in processing. They are the main targets for controlling and reducing emissions in printing and dyeing wastewater.

The quality of wastewater from printing and dyeing factories varies with different raw materials, production varieties, production processes, and management levels. The pH value of general printing and dyeing wastewater is 6-10, COD (chemical oxygen demand) is 400-1000mg, BOD (biochemical oxygen demand) is 100-400mg, SS (suspended solids) is 100-200mg, and chromaticity is 100-1000 times. Overall, printing and dyeing wastewater has the main characteristics of large wastewater volume, deep color, strong alkalinity, complex water quality, and large changes in water quality and quantity.

The flocculation Decolorizing Agent developed by our company can achieve the best decolorization rate of 99% respectively for actual printing and dyeing wastewater, with excellent decolorization performance: the treatment effect under acidic conditions is better than that under alkaline conditions; When used in conjunction with inorganic low molecular weight flocculants, it can produce a synergistic effect and accelerate the flocculation settling rate during treatment. This product belongs to a water-soluble cationic resin, which is a thick and transparent gel like liquid. The larger the polymer molecules, the higher the thickness. It can be mixed with water in any proportion, and when encountering strong acids, strong bases, hard water, etc., it is prone to produce white precipitates. After reaching a certain molecular weight, its solubility in water will decrease.
